I accidentally set an object as camera, how do I undo this?
If you accidentally set an Object as Camera (CtrlNumpad 0 will do that)

You have two options to reset the camera back to the &quot;active camera&quot;

In properties windows/scene select your camera as &quot;camera&quot;




Or on the 3D layout select the camera and press
CtrlNumpad 0 (or use the menu: View-&gt;Cameras-&gt;Select_Active_Object_as_Camera)
